The event runs from 11am to 5pm, with the capital's main thoroughfare closed to traffic until 8pm.

“The reimagining of the period for today will help set the stage for many important conversations about our national identity and cultural roots,” said a RTE spokesperson.

A restored open-front tram will serve as a platform for readings and performances, while the street will also feature an oversized gramophone, a vintage carousel, a steam engine and – weather permitting – a hot-air balloon.

Actors will recreate a period wedding at one end of the street, and a funeral with a horse-drawn hearse at the other.

For those who are unable to come to O’Connell Street on the day, the event will be brought to audiences through live broadcasts from O’Connell Street including The History Show, Arena, Cormac ag a Cúig, on RnaG and coverage on News Now.

The Book Show, Sunday Miscellany, The Poetry Programme, RTÉ One’s Nationwide will also be recording special programmes from the event for broadcast at a later date.

All eight episodes of RTE's drama 'Insurrection', made to mark the 50th anniversary of the Easter Rising, will be shown at Liberty Hall.

The drama has not been shown for almost 50 years and is a telling of the Rising as it might have unfolded had television existed in 1916.

At the GPO, the National Library’s team of archivists and historians invite the public to bring along items of interest connected with the Rising, where they can discuss how they would like to have their family memorabilia recorded for future generations.
